He'll get a kick out of this comic strip-inspired high top. It features an all canvas upper with bold graphics and glow-in-the-dark details, laces for good fit, canvas lining, padded insole, and a built-up, non-marking outsole. Manmade materials. Glow-in-the-dark accents are decorative only and not meant to be a safety feature that will enhance the wearer's visibility at night. Glow-in-the-dark products require a 2-hour charge in sunlight or artificial light before they will glow.
